Illinois Route 100 closed in Grafton

GRAFTON - The Illinois Department of Transportation announced Friday that Illinois Route 100 (the Great River Road) has been closed in Grafton because of flooding on the Mississippi River.

A road closure alert from IDOT said motorists would need to utilize the currently marked detour - Illinois Routes 3, 109 and 16 - to circumvent the closure. Local access to the towns of Grafton, Elsah, Chautauqua and Beltrees is available via Route 3.

Route 100 in Grafton has been designated by IDOT as being closed by high water several times this year, but city officials emphasize that almost all of the businesses along the River Road remain accessible. The closure usually affects a short stretch of the road along the lowest-lying area of the village near the Hawg Pit BBQ Barn.

The Brussels Ferry also remained closed Friday because of flooding.

IDOT officials said they would continue monitoring state roads in the counties of Calhoun, Greene, Jersey and Madison throughout the weekend. Flooding has required closure of state highways and ferries along the Illinois and Mississippi rivers. During the next several days, IDOT will provide updates, as warranted, when developments occur.

Traffic control devices and directional signage, including dynamic message boards, have been deployed to guide motorists safely around major closures. Travelers are advised to consider alternate routes or allow additional time to travel known flood-prone areas.

A dynamic message board set up Friday along Landmarks Boulevard in Alton near its intersection with Route 100 notified motorists that the River Road was closed "north of Grafton" because of high water.
